80 lowpoly heads for NPC crowd

We created 80 lowpoly heads for an unreal engine game. In this project we created male, female and child heads from different races such as Middle East, Russian, Asian and African.
Also we modeled 80 cloth sets for this heads. By this way you can assign each head to any cloth and achieve huge amount of variation.
This chars are rigged by default unreal engine Mannequin skeleton.
